tqdm - Man Page
fast, extensible progress bar for Python and CLI
Synopsis
tqdm [options]
Description
See <https://github.com/tqdm/tqdm>. Can be used as a pipe:
$ # count lines of code $ cat *.py | tqdm | wc -l 327it [00:00, 981773.38it/s] 327 $ # find all files $ find . -name "*.py" | tqdm | wc -l 432it [00:00, 833842.30it/s] 432 # ... and more info $ find . -name '*.py' -exec wc -l \{} \; \ | tqdm --total 432 --unit files --desc counting \ | awk '{ sum += $1 }; END { print sum }' counting: 100%|█████████| 432/432 [00:00<00:00, 794361.83files/s] 131998
Options
- -h, --help
Print this help and exit.
- -v, --version
Print version and exit.
- --desc=desc
str, optional. Prefix for the progressbar.
- --total=total
int or float, optional. The number of expected iterations. If unspecified, len(iterable) is used if possible. If float("inf") or as a last resort, only basic progress statistics are displayed (no ETA, no progressbar). If
gui
is True and this parameter needs subsequent updating, specify an initial arbitrary large positive number, e.g. 9e9.- --leave
bool, optional. If [default: True], keeps all traces of the progressbar upon termination of iteration. If
None
, will leave only ifposition
is0
.- --ncols=ncols
int, optional. The width of the entire output message. If specified, dynamically resizes the progressbar to stay within this bound. If unspecified, attempts to use environment width. The fallback is a meter width of 10 and no limit for the counter and statistics. If 0, will not print any meter (only stats).
- --mininterval=mininterval
float, optional. Minimum progress display update interval [default: 0.1] seconds.
- --maxinterval=maxinterval
float, optional. Maximum progress display update interval [default: 10] seconds. Automatically adjusts
miniters
to correspond tomininterval
after long display update lag. Only works ifdynamic_miniters
or monitor thread is enabled.- --miniters=miniters
int or float, optional. Minimum progress display update interval, in iterations. If 0 and
dynamic_miniters
, will automatically adjust to equalmininterval
(more CPU efficient, good for tight loops). If > 0, will skip display of specified number of iterations. Tweak this andmininterval
to get very efficient loops. If your progress is erratic with both fast and slow iterations (network, skipping items, etc) you should set miniters=1.- --ascii=ascii
bool or str, optional. If unspecified or False, use unicode (smooth blocks) to fill the meter. The fallback is to use ASCII characters " 123456789#".
- --disable
bool, optional. Whether to disable the entire progressbar wrapper [default: False]. If set to None, disable on non-TTY.
- --unit=unit
str, optional. String that will be used to define the unit of each iteration [default: it].
- --unit-scale=unit_scale
bool or int or float, optional. If 1 or True, the number of iterations will be reduced/scaled automatically and a metric prefix following the International System of Units standard will be added (kilo, mega, etc.) [default: False]. If any other non-zero number, will scale
total
andn
.- --dynamic-ncols
bool, optional. If set, constantly alters
ncols
andnrows
to the environment (allowing for window resizes) [default: False].- --smoothing=smoothing
float, optional. Exponential moving average smoothing factor for speed estimates (ignored in GUI mode). Ranges from 0 (average speed) to 1 (current/instantaneous speed) [default: 0.3].
- --bar-format=bar_format
str, optional. Specify a custom bar string formatting. May impact performance. [default: '{l_bar}{bar}{r_bar}'], where l_bar='{desc}: {percentage:3.0f}%|' and r_bar='| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, ' '{rate_fmt}{postfix}]' Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt, percentage, elapsed, elapsed_s, ncols, nrows, desc, unit, rate, rate_fmt, rate_noinv, rate_noinv_fmt, rate_inv, rate_inv_fmt, postfix, unit_divisor, remaining, remaining_s, eta. Note that a trailing ": " is automatically removed after {desc} if the latter is empty.
- --initial=initial
int or float, optional. The initial counter value. Useful when restarting a progress bar [default: 0]. If using float, consider specifying
{n:.3f}
or similar inbar_format
, or specifyingunit_scale
.- --position=position
int, optional. Specify the line offset to print this bar (starting from 0) Automatic if unspecified. Useful to manage multiple bars at once (eg, from threads).
- --postfix=postfix
dict or *, optional. Specify additional stats to display at the end of the bar. Calls
set_postfix(**postfix)
if possible (dict).- --unit-divisor=unit_divisor
float, optional. [default: 1000], ignored unless
unit_scale
is True.- --write-bytes
bool, optional. Whether to write bytes. If (default: False) will write unicode.
- --lock-args=lock_args
tuple, optional. Passed to
refresh
for intermediate output (initialisation, iterating, and updating).- --nrows=nrows
int, optional. The screen height. If specified, hides nested bars outside this bound. If unspecified, attempts to use environment height. The fallback is 20.
- --colour=colour
str, optional. Bar colour (e.g. 'green', '#00ff00').
- --delay=delay
float, optional. Don't display until [default: 0] seconds have elapsed.
- --delim=delim
chr, optional. Delimiting character [default: '\n']. Use '\0' for null. N.B.: on Windows systems, Python converts '\n' to '\r\n'.
- --buf-size=buf_size
int, optional. String buffer size in bytes [default: 256] used when
delim
is specified.- --bytes
bool, optional. If true, will count bytes, ignore
delim
, and defaultunit_scale
to True,unit_divisor
to 1024, andunit
to 'B'.- --tee
bool, optional. If true, passes
stdin
to bothstderr
andstdout
.- --update
bool, optional. If true, will treat input as newly elapsed iterations, i.e. numbers to pass to
update()
. Note that this is slow (~2e5 it/s) since every input must be decoded as a number.- --update-to
bool, optional. If true, will treat input as total elapsed iterations, i.e. numbers to assign to
self.n
. Note that this is slow (~2e5 it/s) since every input must be decoded as a number.- --null
bool, optional. If true, will discard input (no stdout).
- --manpath=manpath
str, optional. Directory in which to install tqdm man pages.
- --comppath=comppath
str, optional. Directory in which to place tqdm completion.
- --log=log
str, optional. CRITICAL|FATAL|ERROR|WARN(ING)|[default: 'INFO']|DEBUG|NOTSET.
